Santa Marta Brushfinch

Overview

The Santa Marta brushfinch (Atlapetes melanocephalus) is a species of New World sparrow endemic to the Sierra Nevada de Santa Marta in northern Colombia. It is a year-round resident that is currently classified as Least Concern by the IUCN, despite its restricted distribution.

Identification

• Adults feature a mostly black head with a silvery gray ear patch, olive gray upperparts, and lemon yellow underparts washed with olive on the flanks.
• Approximately 17 cm in length and weighing around 28 g, with a pale gray or black bill and dusky pink legs.
• Juveniles appear duller with brownish upperparts and buffy yellow underparts marked with thin dusky streaks.
• Vocalisations include two or three loud sweet notes, often delivered in duets as buzzy sequences, alongside sharp tsip or chip calls.

Habitat

This species inhabits humid montane forests, brushy pastures, shade coffee plantations, and gardens within the isolated Sierra Nevada de Santa Marta. It prefers forest edges over the interior and is typically found at elevations between 1,500 and 3,200 m, though it can descend locally to 600 m.

Diet

Specific dietary and foraging behaviours have not been extensively studied, but observations indicate the bird feeds on insects, seeds, and small fruits. It forages on and near the ground, either in pairs, small groups, or as part of mixed-species flocks.

Did you know?

Although the species is assessed as Least Concern with a stable population and no immediate threats, it is considered vulnerable in the long term due to its very restricted distribution and potential susceptibility to habitat loss.
